Cruise Control
With cruise control, you can maintain a speed of
about 25 mph (40 km/h) or more without keeping
your foot on the accelerator. This can really help on
long trips. Cruise control does not work at speeds
below about 25 mph (40 km/h).
{CAUTION:
Cruise control can be dangerous where
you cannot drive safely at a steady speed.
So, do not use your cruise control on
winding roads or in heavy traffic.
Cruise control can be dangerous on
slippery roads. On such roads, fast
changes in tire traction can cause
excessive wheel slip, and you could
lose control. Do not use cruise control
on slippery roads.If your vehicle is in cruise control when the traction
control system, if your vehicle has this feature,
begins to limit wheel spin, the cruise control will
automatically disengage. SeeTraction Control
System (TCS) on page 283. When road conditions
allow you to safely use it again, the cruise control
can be turned back on.
The cruise control
buttons are located
on left side of the
steering wheel.
T(On/Off):Press this button to turn cruise
control on and off. The indicator will be lit
when cruise control is on.
167

+ RES (Resume/Accelerate):Press this button
to make the vehicle accelerate or resume to
a previously set speed.
SET–:Press this button to set the speed or
make the vehicle decelerate.
[(Cancel):Press this button to cancel cruise
control.
Setting Cruise Control
Cruise control will not work if the parking brake is
set, or if the master cylinder brake uid level is low.
The cruise control light on the instrument panel
cluster will come on after the cruise control
has been set to the desired speed. See
Instrument Panel Cluster on page 194.
{CAUTION:
If you leave your cruise control on when
you are not using cruise, you might hit a
button and go into cruise when you do
not want to. You could be startled and
even lose control. Keep the cruise control
switch off until you want to use cruise
control.
1. Press the cruise control on/off button.
2. Get up to the speed you want.
3. Press and release the SET– button located on
the steering wheel.
4. Take your foot off the accelerator.
168

Resuming a Set Speed
Suppose you set the cruise control at a desired
speed and then you apply the brake. This shuts off
the cruise control, but it does not need to be reset.
Once you are driving about 25 mph (40 km/h) or
more, press the +RES button on the steering
wheel. The vehicle will go back to your chosen
speed and stay there.
Increasing Speed While Using Cruise
Control
To increase the cruise speed while using cruise
control:
Press and hold the +RES button on the
steering wheel until you reach your new
desired speed, then release it.
To increase vehicle speed in small increments,
press the +RES button.
Reducing Speed While Using Cruise
Control
To reduce your speed while using cruise control:
Press and hold the SET– button on the
steering wheel until you reach the lower
speed you want, then release it.
To slow down in very small amounts, press
the SET– button on the steering wheel
briey. Each time this is done, you will
go about 1 mph (1.6 km/h) slower.
Passing Another Vehicle While Using
Cruise Control
Use the accelerator pedal to increase vehicle
speed. When you take your foot off the pedal, the
vehicle will slow down to the cruise speed you
set earlier.
169

Using Cruise Control on Hills
How well the cruise control will work on hills
depends upon the vehicle speed, load and the
steepness of the hills. When going up steep hills,
you may have to step on the accelerator pedal
to maintain your speed. When going downhill, you
may have to brake or shift to a lower gear to
keep your speed down. Of course, applying the
brake ends the cruise control. Many drivers
nd this to be too much trouble and do not use
cruise control on steep hills.
Ending Cruise Control
There are three ways to end cruise control:
Step lightly on the brake pedal.
Press the[(cancel) button on the steering
wheel.
Press theT(on/off) button on the steering
wheel.
Erasing Speed Memory
The cruise control set speed memory is erased by
turning off the cruise control or the ignition.
Exterior Lamps
The exterior lamps
control is located on
the instrument panel
to the left of the
steering wheel.
It controls the following systems:
Headlamps
Taillamps
Parking Lamps
License Plate Lamps
Instrument Panel Lights
Fog Lamps

wx(Driver’s Temperature Controls):Press
these buttons next to the fan control to manually
increase or decrease the temperature inside
your vehicle.
wx(Passenger’s Temperature Controls):
Press these buttons next to the mode control to
manually increase or decrease the temperature for
the front passenger. If the passenger’s climate
control system is off, pressing one of these buttons
will turn it on.
PASS (Passenger’s Climate Control):Press
this button to turn the passenger’s climate control
systems on or off.
If the PASS button is pressed to turn the
passenger temperature setting off, the driver’s
temperature setting will control the temperature
for the entire vehicle.
Sensors
The solar sensor, located in the defrost grille,
middle of the instrument panel, monitors the solar
radiation. Do not cover the solar sensor or the
system will not work properly.
There is also an interior temperature sensor
located next to the steering wheel that measures
the temperature of the air inside your vehicle.

Outlet Adjustment
Use the levers, located in the middle of the front
outlets, to change the direction of the airow.
Use the thumbwheel located between the outlets
to turn them on and off.
If your vehicle has rear seat outlets, adjust the
direction of the airow using the lever in the center
of each outlet.
Operation Tips

Clear away any ice, snow, or leaves from the
air inlets at the base of the windshield that
could block the ow of air into your vehicle.
Use of non-GM approved hood deectors can
adversely affect the performance of the system.
Keep the path under the front seats clear of
objects to help circulate the air inside the
vehicle better.
Passenger Compartment Air Filter
The passenger compartment air lter traps most of
the pollen from the air entering your vehicle. Like
your vehicle’s engine air cleaner/lter, it may need
to be changed periodically. For how often to change
the passenger compartment air lter, see
Scheduled Maintenance on page 442.
The access panel for the passenger compartment
air lter is located under the hood near the
windshield, on the passenger’s side of the vehicle.

Anti-Lock Brake System
Warning Light
With the anti-lock brake
system, the light(s) will
come on when your
engine is started and
may stay on for
several seconds.
That’s normal.
If the light stays on, turn the ignition to OFF. Or, if
the light comes on when you’re driving, stop as
soon as possible and turn the ignition off. Then start
the engine again to reset the system. If the light still
stays on, or comes on again while you’re driving,
your vehicle needs service. If the regular brake
system warning light isn’t on, you still have brakes,
but you don’t have anti-lock brakes. If the regular
brake system warning light is also on, you don’t
have anti-lock brakes and there’s a problem with
your regular brakes. SeeBrake System Warning
Light on page 201.
The anti-lock brake system warning light will come
on briey when you turn the ignition key to RUN.This is normal. If the light doesn’t come on then,
have it xed so it will be ready to warn you if there
is a problem.Traction Control System (TCS)
Warning Light
This warning light
should come on briey
when the engine is
started.
If the warning light does not come on then, have it
xed so it will be ready to warn you if there is a
problem. If it stays on, or comes on when you are
driving a SERVICE TRACTION CONTROL
message will appear in the Driver Information
Center (DIC). This indicates that there may be a
problem with your traction control system and your
vehicle may need service. When this warning light
is on and the SERVICE TRACTION CONTROL
message appears on the DIC, the system will not
limit wheel spin. Adjust your driving accordingly.
